Topic Molecular Simulations of Crystal Nucleation in a System of Binary Hard Spheres
Date 03,October 2015 (Friday)
Place L-17 Lecture Hall Complex (LHC)
Time
4 pm. - 5 pm.

ABSTRACT
Crystal Nucleation is the primary mechanism for phase transformation from fluid to solid phases. Despite its widespread occurrence, our understanding of the mechanisms of nucleation is far from complete. In this talk, I will be discussing methods to study crystal nucleation using molecular simulations and the application of these techniques to system of binary hard spheres.

Hard sphere represent the computationally easiest system that shows fluid-solid phase transition and the phase diagrams of binary hard sphere mixtures can show complex features such as azeotrope formation, eutectic points, co-crystal formation, etc. Through our simulations I will show how that the underlying phase diagram strongly influences the mechanism and pathway for crystal nucleation.
